Whitworth Coarse Thread BS 84 BSW (British Standard Whitworth) British Standard Whitworth Coarse Thread Series (parallel, cylindrical) In GB most common Thread. For plug gauges, a plus tolerance is applied to the GO member and a minus tolerance to NOGO member. The class tolerance determines the size of the gap between the pitch diameters of the internal and external thread. 6H or any other class as per customer requirement: Thread Ring Gauges. The No Go element tests only that the Effective diameter is not too large (minimum material limit). If the finished tapped hole gages satisfactorily, the installed insert will be within the thread tolerance. As an example, a common screw thread tolerance is 5g6g, which has a 5g tolerance on its pitch diameter, and a 6g tolerance on its external diameter. For internal threads class 6G may be used as a pre-plating condition for 6H after plating. It specifies the features of the types of gauges (Solid/adjustable GO screw ring gauges, check plugs, setting plugs, wear check plugs, screw caliper gauges, plug gauges, etc.) The basic profile of the ISO threads is shown below. Tolerance Direction Cylindrical Ring Gage Go Member is to the minus side, Nogo Member is to the plus side. The nut and bolt deviations and tolerance zones are illustrated here.
